as established by the current EU and ROTS: a sith lord(or lady) with mechanical parts cannot summon Force lightening due to the fact that it would destroy the circuts and cause the limb to be useless.

yet in Jedi, Luke is pummeled to the floor by Darth Sidious's onslaught of dark force lightening and after this massive amount of torture. his mechanical hand still works? i mean yeah yeah it took a blaster shot on the barge, but this really contradicts established lore.

are we supposed to believe Luke's hand is the only one capable of withstanding this? we can't write it off as more advanced than Vader's whole BODY or lumiyas imperial funded cybernetic replacements can we? also since thirty-seven years later in LOTF this is still the case. so....?

i've finnally made it through the prequels on dvd.starwars.com, not really worth the effort but atleast the feature can work, but the original trilogy dvds only have script to screen, which is kinda annoying? so did they they ever have the depth commentary or did they cheap out? or is it the fact that i got the trilogy set that came out last year sans disc four.
